Estimation of the dietary essential amino acid requirements of colliroja Astyanax fasciatus by using the ideal protein concept

open access: yes, 2015
Colliroja, Astyanax fasciatus, is a new aquaculture species, and information on its dietary essential amino acid requirements is lacking. The whole body composition of 120 farmed fish (16.2 ± 8.8 g) was determined to estimate the dietary essential amino ...
